To all whom it may concern: I g

. Be'it known thatI, HO ACE TL THOMAS, citizen of the United States, residingatf Lansing, county ofIngham, State of Mich gan, have invented a certain new and useful Improvement in Oiling Systems for Automobile Engines, andjdeclare the fol' lowing to be afull, clear, andexactdescription of the same, such 'as will enable others skilled in the art to which it pertains to make'and use the same, reference being had to the accompanying drawings,fwhichform; a part of this specification;

My invention relates to an for automobile engines. y

In the accompanying drawings: I

Fig. 1 is a plan View of the oil receiving an. P Fig. 2 is a section to an enlarged scale of a part of the lower portion of the crank case. a

Fig. 3 is a cross section of the same showing also a crank and part of a connecting rod. i

Fig. 4 is a perspective view of the oil shielding strip.

Fig. 5 is an elevation of the oil distributing plate.

Fig. 6 is a section on the line VIVI Fig.

Fig. 7 is a perspective view of a portion of the oil distributing plate.

Fig. 8 is a perspective view of the securing rib of the oil distributing plate.

a is the crank case; a the oil well or oil receptacle portion of the crank case; a is the crank; a the connecting rod and a the dipper extending downwardly from. the lower end of the connecting rod. These are conventional constructions.

b is the oil receiving pan. This is provided with transverse depressions b in its upper surface. The oil is forced from the receptacle a to the different bearings in the crank case and falls from said bearings upon the surface of the pan 6 and flows therefrom into the depressions b 0 is a rectangular plate having a longitudinal slot 0 therein. A plate 0 is placed over each of the depressions b so that the slot shall extend the length of said depression concentric therewith and the plate shall partly cover said depressionuponv each side, the. slot being of sufficient breadth and length to permit the dipper a to enter therein and dip into the oil and spray it, during the oiling system 19 21.1.

" revolution'of the crank. The'plate'c is preferably sunk intothe surface of theoil receiving plate?) as indicated in'Fig. 2 so that the oil which fallsion the surface of the latter shall flow without obstruction into a slot 0 and into the receptacle 6 The plate 0 partly covers the receptacle 6 upon both sides so that as the "dipper passes through said depression and slot, the'oil' which would otherwise be thrown up laterally is obstructed'by the side portions of the plate 0 and returns to the bottonrof the receptacle. I d is a plate, the form of which is distinctly shown in .the drawings. The plated is secured upon" that side 'of thecrank case toward which the crank a turns a's clearly shown in Fig. 3, andis bent outward at its lower part as shown in Fig. 3 to bring its lower edge adjacent to the oil receptacle b The'plate d is turned over at its upper edge as indicated in Fig. 2 to catch the oil thrown against said plate which would otherwise flow over its upper edge. Said plate is turned upward at its ends as indicated at d.

The plated is notched at intervals as indicated at 0% at its lower edge and the portion of its edge between said notches is turned upward to form a trough as indicated at 03 When the plate (I is secured in place, a notch d comes opposite each of the slots 0 The operation of the above described device is as follows:

As the crank shaft revolves, the dipper a it passes through a slot 0 and throws the oil laterally against the plate d. The oilthus thrown against the plate is prevented from flowing over the upper edgeof said plate as above described by the overturned upper edge and flows by gravity downward to be received by the upturnedlower edge (i and constrained to flow through the notches or openings (1 immediately adjacent to the slots 0 through which slots the oil returns immediately to the receptacle 5.

Claims i 1. In an apparatus of the kind described,

a sheet metal oil pan having a depression b therein, a sheet metal strip separate from said pan secured to and lying flat upon the surface of said pan, its edge extendin'gover said pan secured to and lying flat upon the surface of said pan upon each side of said depression, its edge extending over the edge of said depression, for the purpose described.

8. In apparatus of the kind described, an"

ing cut away to form a dischargepassage for oil at a point adjacent to the end of said depression.

4; In apparatus of the kind described, an

oil pan having a depression b therein, a

sheet metal plate located upon one side of said pan and having its'lower edge turned of said depressions, said up-turned portion upward to form a trough parallel to the surface of said pan, said up-turned'edge being cut away to form a discharge passage for oil at a point adjacent to the end of said depression, theupper edge of said plate be-' Qing also turned over to form an inverted trough, for the purpose described.

5. In apparatus .of the kind described, an

fication'.

oil pan having a depression therein, a sheet metal plate located upon one side of said pan and having its lower edge turned upward to form a trough parallel to the surface of said pan, said up-turned edge being cut away to form a dis-charge passage foroil' at a-point-adjacent to the end of said depression, in combination with the strips 0,

substantially as and for the purpose described.

6. In an apparatus of the kind described, an oil pan having a plurality of parallel depressions 6 a sheet metal plate located in an upright position at one sideof said pan and having its lower edge upturned to form a trough parallel to the surface of said panextending past and adjacent to the ends being cut awayto form a discharge passage for the oil opposite the end of each ofsaid depressions, substantially as and for the purpose described.

In testimony whereof, I sign this speci- HORACE T. THOMAS.
